Advanced Building Diagnostics with Thermal Imaging
The PRIMARY DIAGNOSTIC PROCEDURE for determining the thermal performance of a building envelope is infrared thermography. It can be used to identify heating and cooling loss due to poor construction, missing or inadequate insulation and moisture intrusion.
Thermal Performance Analysis - THE MOST ACCURATE METHOD
Result: Correcting the defects plays a significant role in increasing building efficiency and structural integrity.
Determine thermal performance of building envelope
Identify energy loss due to poor construction
Detect missing or inadequate insulation
Early detection of water infiltration
Professional Roofing Thermal Analysis - MOST ACCURATE LEAK DETECTION
Flat roof membranes are the waterproof barriers between the outside elements and the interior of buildings. Our thermal imaging technology provides the MOST ACCURATE leak detection available.
Inspect flat roof membranes and waterproofing
Identify roof leaks before they cause damage
Assess various roofing materials and designs
Evaluate expansion, contraction, and wind resistance
Why Roofs Leak - THERMAL IMAGING REVEALS THE TRUTH
Roofs must be able to expand and contract, resist high winds and the effects of solar radiation and withstand foot traffic. Our thermal imaging technology makes it easy to see why roofs leak.
Advanced Thermal Detection - SEE WHAT OTHERS MISS
Our STATE-OF-THE-ART thermal imaging technology provides comprehensive building analysis, identifying energy loss, moisture intrusion, and structural issues that are INVISIBLE TO THE NAKED EYE.

Professional Mold and Moisture Detection - EARLY DETECTION SAVES MONEY
Mold has existed in our environment long before the recent awareness of its presence in homes and businesses. Our thermal imaging technology provides EARLY DETECTION that can save thousands in repair costs.
Health Risks and Effects - THERMAL IMAGING REVEALS THE HIDDEN DANGER
Federal Legislation
The mold topic has reached such proportions that congress has introduced a bill titled "United States Toxic Mold Safety and Protection Act of 2002" also known as the "Melina bill."
Allergic reactions, asthma, and respiratory issues
Effects depend on spore concentration and allergies
Moisture accumulation from condensation or leaks
United States Toxic Mold Safety and Protection Act
